To all whom it may concern: I

Be it known that we, HENRY A. CARPEN- ran and Anrnnn W. Wanner, citizensof the residing at Sewickley, 1n the,

United States, county of Allegheny and State of Pennsyl- Vania, haveinvented certain new and useful Opermcion Improvements in Means ofGas-Retorts, lowing is a specification. I

lhe charging and discharging of gas making retorts necessitate properlyplacing the mechanisms which are involved in such operations. This istrue of the discharge end of the retort as well as its inlet end,particularly if the discharge is into a producer charging machine, itbeing necessary to have the latter in receiving position before thescoop or other tool is entered in the retort. A premature operationendangers the mechanism and is liable to resultin injury to the producercharger operator. Q

The primary object of the present invention is to insure the properpositioning of the producer charger or other coke receiving means beforethe retort tool can be operated. In the present embodiment, this isaccom plished by providing a controlling circuit for the tool actuatingmotor, with an interruption therein which is closed by ducer chargingmachine only when' in alinefor Controlling the of which thefolment-with' the retort and in proper position to receive the cokedischarged therefrom. This controlling circuit may also be provided.with other interruptions for auxiliary controlling devices, one of whichmay be closed by the retort charging machine when the tool is inalincment with the retort to. be operated upon, and other interruptionsmay be controlled by the retort doors. While these auxiliary controllingdevices may, be 7 used in conjunction with the control effected by theproducer charger or other coke receiving means, the latter may be usedalone and without regard to such auxiliary devices.

It is a further ant invention that the the apparatus is mounted on theretort charging machine, which however, is operative only when thecontrolling circuit has been closed as a result of properly position ingthe producer charger, and only after the auxiliary controlling deviceshave been manual control for bench and 3 one of a series the pro- 3 bythe trolleys a,

D and E are conductors for the tool motorit will be understood thatcharacteristicof the presplaced in tool operating position if such do avices are employed In the accompanying drawin Figure 1 is a diagrammaticillustration 0 a form 0 apparatus embodying the invention. Fig. 2 is adetail of the circuit closing means associated' with one of theretort-doors.

Referring to the drawings, 2 designates a of retorts therein. the frameof a retort chargwhich is movable along the y designates ing machinefront of the bench on track 5, Mounted in any suitable manner on thetraveling charging machine is a carriage 6 for a charging anddischargingscoop or other retort tool 7, Carriagefi may be actuated ontrack 8 by a threaded shaft 9 which extends through a nut or head 10 ofthe carriage, shaft 9 being geared at 11 to an electric motor 12. Alsogeared at 13 to shaft 9 is a screw shaftll, the rotation of which slidesthe contact bar lo-relativcly to certain circuit terminals, as will bepresently explained. Any suitable means, as an electric motor 16, may beutilized for movingthe retort charging machine on track 5.

At the opposite'side of the bench, 17 in-- dicates gas producerssurmounted by track 18 on which moves the producer-charging machinewhich may include the laterally movable transfer receptacle 20.

lhe apparatus three-phase electric system having three conductors A, Band C, for the retort charging machines which, Eespeptively, are engagedcontrolling cir' buit, hereinafter described, and engaging the same aretrolleys (Z and 6, respectively. e

A double or reversing solenoid switch 25 directs the current to the toolactuating motor 12, the forward movement being controlled by solenoid 26andthe F backward movement by solenoid 27. This double solenoid switchis of usual and well known construction. Mountedin any suitable manneron the retort charging machine is the manu-- ally operated controller Zwhich may be -moved to place its circuit closing arm Z in two positions,one for efi'ccting the retortentering movement of the tool 7 and theother for retracting the tool.

The wiring for motor 12 and switch 25 is preferably embodies a switcl25; wire 29'from trolley b to switch t tool is in alinement with thecarriage.

, follows :Wire 23 fr omtrolley a leads to fuch operation cannottake-place a 25;: .wire 30 from trolley to motor 12. :Tracing thecircuit for forward solenoid 26, the upper terminal thereof is connectedby wire 29 to. trolley b, and wire 31 from the other end of the solenoidextends to trolley'll andconductor D to the rearrand front of bench 2,then to conductor E, trolley e, and to contact arm 37 of the slid ingswitch, with an interruption 35"at controller Z. From contact arm 37 thecircuit is continued through sliding contact bar to contactarni, 38 andthroughwire'31" to 15 wire 30 which connects with trolley c.

The circuit for the backward or re- ,versing solenoid 27 is. as follows:One end.

of this solenoid is connected by wire 29'leadingto trolley 12.. Theother end of the sole-- noid is connected by wire 56 to contact arm 57of the sliding switch, with anjinterruption 35 at controller Z. With bar15 in engagement with contact arm 57, as it is when the bar is depressedand the tool entered 2 6 -the retort, the backward circuit is throughthe contact bar, contact arm'38, and branch wire 31' towire andtrolley'c..

The port-ion of the controlling circuit 31 which extends to the bench isprovided pri- 30 marily with ,an interruption 60 which is adapted to bebridged by the circuit clos- 'ing device 61 on theproducer chargertransferreceptacle 2O When'the latter has been properly positionedbeneath a retort for receiving the coke discharged therefrom,

Thus, it will be seen'that unless the retort charging 'machine'isinproper position the forward solenoidt26 cannot be operated even thoughthe manual controller Z is 1 moved to bridge circuit interruption 35. Itis characteristic ofa preferred adaptation of the invention to locatecontrollerZ on the retort charging machine and to have the same operatein "conjunction with the circuit' closer carried by the producercharger,

so that the operator cannot cause the tool to enter the retort untilafter the producer charger has been properly positioned.

Circuit 31 may if desired .have additional interruptions at the bench,such as interrupti on 62 for therear door of-the retort, interruption 63for the front door of the retort, and interruption for the retortcharging machine, a circuit closing device 65 being 25 adapted to bridgeinterruption 6,4 when said machine is in position toaline tool 7 withthe retort. .The'door 66,-Fig.v 2, maybe the door for either the inletor the discharge end of the retort, with an arm 67 projecting therefromwhich isadapted to bridge'in-' terrupti-on 62', or interruption 63,-whenthe doors'are 0 en, thereby makingfit impossible for a orwardmovement-of the tool to ensue untilboth thefrontrand rear doors 65 havebeen opened. And with interruption the outer limit of its movement,- asin 1, it .leaves arm 57, thereby opening the He the several auxiliarycontrolling means, embodying interruptions. 62, 63 an 64 maybe usedseverally or collectively in connection with interruption60, it will beted,as will be understood.

The contact arms 37,

to a standstill in: withdrawn position. As I bar 15"approaches theinward limit ofv its travel, it coasts off of arm 37, thereby openingtheforward; circuit and stopping the tool, but leaving her 15 in engagementwith contact arms 38 and 57 in readiness for the backward traverse ofthe tool when conti'oller Z is thrown to close interruption 35.
